The CPU I is monitored the detecting sensor group of detecting unit and the input state information of manual control unit in real time through load module, thereby judges whether to have taken place disaster or the people is for supressing alarm button; Disaster or people having been taken place when supressing alarm button when monitoring, drives the detection alarm unit through output module and send alerting signal, and note the date and time that disaster or manual work take place; The CPU I is carried out exchanges data through serial ports and charge book analysis and management system VIII simultaneously, when the command information that receives from serial ports, can carry out refresh clock according to the type of command information, uploads data, operation such as obliterated data; Its idiographic flow is:
AS1: system initialization;
AS2: the house dog that CPU I chip integration is become carries out dog feeding operation;
AS3: judge whether to have taken place automatic warning,, otherwise jump to aS6 if then jump to aS 4;
AS 4: through the I/O mouth output alarm signal of output module I;
AS 5: automatic warning message is recorded among the EEPROM of CPU I chip integration one-tenth;
AS6: judge whether to have taken place manual alarm operation, if then jump to aS
7, otherwise jump to aS9;
AS 7: through the I/O mouth output alarm signal of output module I;
AS 8: manual warning message is recorded among the EEPROM of CPU I chip integration one-tenth;
AS 9: judge whether to have taken place the test alarm operation, if then jump to aS10, otherwise jump to aS12;
AS 10: through the I/O mouth output alarm signal of output module I;
AS 11: will test warning message and record among the EEPROM that CPU I chip integration becomes;
AS 12: judge whether alarm operation has taken place to stop, if then jump to aS13, otherwise jump to aS15;
AS 13: output alarm signal not;
AS 14: the generation information that stops to report to the police records among the EEPROM of CPU chip integration one-tenth;
AS 15: judge whether serial ports has received the command information that host computer sends, if then jump to aS16, if otherwise jump to aS2;
AS 16: carry out according to the content of command information and return aS2 after serial ports is handled subroutine.
Said serial ports is handled subroutine and is comprised that the command information of sending according to the host computer management system software carries out refresh clock, uploads operations such as data or obliterated data.
Said detection alarm unit software uses Keil uVision2 exploitation; Purpose is that control detection alarm unit IV is accomplished the following actions process: the CPU II is through the output information of processing of load module II acquired signal and charge book unit III; In case taking place, disaster or manual work carried out alarm operation; After the CPU II collected signal through load module, control voice module and driving train dispatch radio communication alarm unit sent the voice signal of warning, directly block and stop train;
The concrete steps of detection alarm unit controls process are:
BS1: system initialization;
BS2: feed and see the doorway dog;
BS3: judge whether the key that pushes for emergency, if by the next bS4 that jumps to, not by the next bS2 that jumps to;
BS4: return bS2 after carrying out actuation of an alarm.
Its main innovate point that is used for the method for crag falling rocks warning of crag falling rocks warning system of the present invention is:
1., detect technology after employing reliable detection net column tilts; Crag falling rocks warning system of the present invention is detecting the detection mode of having taked detection net+detecting sensor on the principle; Can reliably detect after the net column tilts in order to make to detect, the present invention adopts obliquity sensor as detecting sensor, and operating angle is 30 degree; This obliquity sensor normal position (vertically) is closure state down, is open-circuit condition in case tilt to 30 degree angles above; Detect on the net column and whenever load onto detecting sensor at a distance from the 8-12 meter ampere; And in the connection of sensor groups, adopted the connected mode of polyphone; All detecting sensors that constitute the detecting sensor group contact into that the monitoring treatment circuit forms a big loop, as long as any one detecting sensor action can both trigger warning.
2., adopt and to have self-diagnostic function testing circuit technology, this circuit has short circuit and open circuit self-checking function, that transmits on the circuit is voltage signal, antijamming capability is strong.
3., reliable alarm technique, the final purpose of crag falling rocks warning system is to send the audio alert signal to the driving driver when harm takes place, and notifies it to take urgent measure; Therefore how to send the audio alert signal reliably and can receive it is a key of this warning system with the driver that guarantees to drive a vehicle; On hardware, use the audio frequency isolating transformer in the present invention's design, increase the reliability of the output of reporting to the police; On the software in case report to the police promptly repeat output alarm signal up to manual work remove report to the police till, be equivalent to increase the function of repeated and redundant from software, significantly reduced and failed to report and leak the possibility of listening;
Crag falling rocks warning system of the present invention and be used for method that the crag falling rocks reports to the police compared with prior art has following beneficial effect:
1, can monitor disaster automatically and take place, in time send warning: one of prior art is to monitor side slope when being subjected to displacement, notifying the keeper, taking corresponding measure by relevant department again; Shortcoming is that monitoring periods is long, and labour intensity is big, reports to the police to have hysteresis quality, and influenced by human factor; The train dispatch radio communication panalarm of on-the-spot acousto-optic panalarm of signal Processing and charge book unit starting and detection trigger alarm unit takes place just in time to pass through in the disaster that native system monitors automatically; The process of whole monitoring and warning is accomplished by system automatically; Need not manual intervention, real-time is stronger.
2, type of alarm is more independent, more reliable: two " geologic hazard detection and warning systems " of prior art need be passed field monitoring data or image to giving directions server or keeper back through modes such as internet or notes when the monitoring disaster; Therefore must use in the effective overlay area of other communication mobile network such as GSM or GPRS network; Rely on the service that the third party provides, if just can't use in the mountain area that does not have signal to cover; And native system is directly to transfer the driving driver in the intercom field intensity coverage to report to the police to getting into row through existing train dispatch radio communication device, does not rely on the service that the third party provides fully; Simultaneously; When finding to have the disaster that jeopardizes train operation, the field staff takes place; And system is not when automatically reporting to the police, and on-the-spot guard also can report to the police through manual control unit direct control equipment or stops to report to the police according to on-the-spot needs, has further increased its reliability.
3, has charge book function (being equivalent to black box function): record is carried out in all operations, can carry out query analysis through computer management system.
4, can make full use of existing apparatus and equipment (like train dispatch radio communication) transformations and use, cost is low, is easy to promote.
5, have good economical, societal benefits: because native system has above-mentioned advantage, therefore, it is along the line to be specially adapted to be installed in the railway that crag falling rocks, landslide or rubble flow possibly take place, and has very strong specific aim; Can effectively detect the disaster generation that crag falling rocks, landslide or this type of rubble flow jeopardize traffic safety; Once just can reduce tens for railway, the economic loss of units up to a million; If passenger vehicle can be avoided the loss of people's lives and properties, meaning is more great.Therefore this system has a good application prospect and economical, societal benefits.
Below, in conjunction with accompanying drawing and embodiment to the present invention's crag falling rocks warning system and the technical characterictic that is used for the method that the crag falling rocks reports to the police be further described.
